Portion of a shoe upper



FIG. 1 is a front perspective view of a portion of a shoe upper showing my new design; and,

FIG. 2 is a side view thereof.

The nine broken line circles in each of the Figures represent an unclaimed portion of the design. The uneven broken line bounding the shaded area represent an unclaimed boundary of the design. The uneven broken line showing of the remainder of the shoe is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a portion of a shoe upper, as shown and described.
